1 piece 5-Pin 12V 30A SPDT cube-style Relay (size: 1.65" x 1.25" x 1.25", the time delay relay box is taller than regular relay box, please see picture-7 to confirm the size before buying)

Allow approx 10 seconds delay to turn on the light

Good for most car/motorcycle retrofit lights that do not have switch or want to delay the turn-on time to protect the battery or circuit/fuse, perfect for high power lighting applications such as LED light bar, LED work lights, HID system, etc

Direct plug in to most 4-pin or 5-pin sockets (since the delay relay is polar sensitive, if it does not trigger the light up, please flip the input wires around, see demo video)

12 V DC automotive waterproof relays (max 14 V). Note: 12 V and 14 V are coil voltages, they are not the voltage that triggers the switch
